hi im having a problem with iroc-z when i idle it kinda feels like its loping and i dont have an aggresive cam its stock.and when i go it feels like it bogs down and wants to die out( never dies though), i have a code reader which gave me code 33 and 36 which are both related to the MAF sensor , i replaced the MAF sensor though and it still runs like sh*t , but it said it could be an electrical short in the circuit or some thing any help is greatly appreciated.
